Slide 8 - Diapositive
Mechanics of BREATHING:
- Abdominal of diaphragmatic breathing
- Thoracic breathing
Slide 9 - Diapositive
Slide 10 - Vidéo
Thoracic inhalation:
air is sucked into the lungs
intercostal muscles contract
ribs pull the plearul membrane open
the plearul membrane pulls open the lungs
ribs move up
Slide 11 - Question de remorquage
Thoracic exhalation:
air is pushed out of the lungs
intercostal muscles relax
ribs push the plearul membrane closed
the plearul membrane pushes the lungs closed
ribs move down
Slide 12 - Question de remorquage
Abdominal inhalation:
air is sucked into the lungs
abdominal muscles contract
the diaphragm moves down
the plearul membrane pulls open the lungs
the diaphragm pulls the pleural membrane open
Slide 13 - Question de remorquage
Abdominal exhalation:
air is pushed out of the lungs
abdominal muscles relax
the diaphragm pushes the pleural membrane closed
the pleural membrane pushes the lungs closed
the diaphragm moves up
Slide 14 - Question de remorquage
Slide 15 - Diapositive
Lung volumes and spirograms
When we breathe air moves into and out of our lungs.
We can measure how much air moves at a time and put these measurements into a graph.
These graphs are called Spirograms.
Take a look at the next slide.
Slide 16 - Diapositive
Slide 17 - Diapositive
Important words:
You do not need to know all the words in the graph only the most important ones.
Vital capacity
Residual volume
Total lung Capacity
Tidal volume
Slide 18 - Diapositive
Vital Capacity:
The maximum amount of air you can move with one large inhalation followed by a large exhalation.
How much is this person's vital capacity?
Vital Capacity
Just under 4 liters.
Slide 19 - Diapositive
Residual Volume:
A small amount of air that always stays behind in the lungs, this is so they do not collapse.
How much is this person's Residual Volume?
Residual Volume
Just over 2 liters.
Slide 20 - Diapositive
Total Lung Capacity:
The maximum amount of air a person's lungs can hold.
How much is this person's Total Lung Capacity?
Total Lung Capacity
6 liters
Slide 21 - Diapositive
Tidal Volume:
The amount of air a person moves into and out of the lungs when relaxed.
How much is this person's Tidal Volume?
Tidal Volume
about 0.8 liters
